Default problem with a compaq preasario on start up

Okay. I'm a tech, working on a client's computer. I've seen similar stuff, but I don't remember how to fix the problem, and hopefully I won't have to go hunting for a new screen for this **** thing.

The problem is, once I get the laptop charged enough, I then press the power button. The POST for windows comes up, then the screen kind of... shimmers, would be the word, I guess, and then it quits and fails. Afterward, I try to hard boot and restart, and it dfoesn't want to turn off or restart. unplug power and battery, so that I canturn the power off. Plug it back into the ac adapter and put the battery back in, and try to immediately start it up again. the processor light flashes, then :P Nothing.

I'm unsure if this is a software or hardware problem, though I was unable to find a problem with the ram, nothing physically wrong with the hard drive, and the screen, before it shimmers and dies, is bright and crisp. Also, if I wait ten minutes, it's the same crap all over again. Can anyone give me some leads? because I was unable to fi9nd anything on google. Help would be most graciously appreciated. Thank you.

Stats on the laptop

unable to even get to bios settings because of screen problems
possibly a virus, maybe the screen itself, but i want some opinions before i continue.
Thank you for your help, in advance.

FYI - POST is a BIOS function, not Windows.

Did you try resetting BIOS?
Is your screen's backlight flickering? Shine a flashlight at the screen. If you see anything on the screen, that is your problem.
At what point does it go out during POST?

I didn't try resetting the bios, and it does get past the POST. It's as it's restarting Vista that it shimmers and dies. Then it's a pain in the *** to try and restart. I'm also able to get into the BIOS itsel with no problems. I seriously think it's a virus, now that I'm reviewing the problem online. But I'm unable to check at the moment, because the client forgot to give me her power cord. going to try and use a BartPE first, to scan it, then if it's verified, I'm going to format and install XP Pro.
